Retries are done by default because keyservers can be unreliable. Additionally, there is no way to determine the difference between a non-existent key and a failure. In both cases gpg (at least 2.2.4) exits with status 2 and stderr: "keyserver receive failed: No data" It is assumed that a key provided to cloud-init exists on the keyserver so re-trying makes better sense than failing. @param key: a string key fingerprint (as passed to gpg --recv-keys). @param keyserver: the keyserver to request keys from. @param retries: an iterable of sleep lengths for retries.
